For my Trio Omega with a basshorns, I am using Antiphon Conductor preamp and Antiphon Monolith monoblocks.
The reason for the Conductor: absolute reference level detail preservation and pre-amplification, uncomparable dynamic scaling, most natural tonality, widest and deepest soundstage formation and leveling capacity.
The reason for the Monoliths: true amplification of whatever fed to, most natural and warmest rendering of tonality, widest and deepest soundstage formation and leveling capacity, tightest and deepest low frequency reproduction (among SET amplifiers) even rivaling the Boulder 2060 amplifier.
